Abstract

Un sistema de telecomunicaciones móvil que comprende terminales móviles de un primer tipo y terminales móviles de un segundo tipo las terminales móviles se disponen para transmitir datos de enlace ascendentes a una red sobre una interfaz de radio usando una pluralidad de sub-portadores y las terminales móviles del primer tipo se disponen del primer tipo se disponen para transmitir datos de enlace ascendentes en un primer grupo de sub-portadores de la pluralidad de sub-portadores sobre un primer ancho de banda y las terminales del segundo tipo se disponen para transmitir datos de enlace ascendentes en un segundo grupo de sub-portadores de la pluralidad de sub-portadores dentro del primer grupo de sub-portadores sobre un segundo ancho de banda. El segundo ancho de banda es menor que el primer ancho de banda. Las terminales móviles del primer tipo se disponen para transmitir mensajes de solicitud de acceso aleatorio a una estación base de la red que solicita recursos de radio de enlace ascendentes en un primer canal de acceso aleatorio. Las terminales móviles del segundo tipo se disponen para transmitir mensajes de solicitud de acceso aleatorio a la estación base de la red que solicita recursos de radio de enlace ascendente en un segundo canal de acceso aleatorio. Los mensajes de solicitud de acceso aleatorio transmitidos en el segundo canal de acceso aleatorio se transmiten en el segundo grupo de sub-portadores.
